This invention concerns improvements in hinged wicket doors for use with rolling shutters, blinds or the like and more particularly to doors of this character which are normally prevented V control.

According to the invention for this purpose the flaps or like stops are connected by links to handle operated mechanism mounted on the door.

Two embodiments of the invention are shown v by way of example in the accompanying drawings,

I stanchion, wall or other fixed portion of the building 9 by means of the hinges 12. When the shutter is lowered the door is swung into the opening or doorway. The door is provided on one side with flanges 11' which engage one face of the shutter 10 to prevent the door passing through the opening or doorway in shutter 10. On the other side of the door there are looking flaps 13. These flaps are mounted on the door by hinges 14 and are attached to bent plates 13a (Figs. 2 and 4) which in turn are hingedly connected at 15 to links 16. These links are pivoted to a lever 17 rigid on a spindle l8 journalled in the door and carrying at each side of the door a handle 19. One link has a slotted lug 20 adapted to be engaged by the latch or bolt 21 of a key-operated lock 22.

Normally the flaps are in the position shown in full lines in Fig. 4 and the links 16 are horizontal, being locked if desired by the latch 21. If, however, the latch being disengaged, either handle 19 is turned, the links move to the dotted line position shown in Fig. 3 and the flaps swing out as shown in dotted lines in Fig. 4 to release the door. By reason of the hinge 12 the door may then be swung completely clear of the shutter.

In the arrangement of Figs. 5 and 6, the flaps are hinged at 23 to the inside of the door and are connected by hinges 24 to the ends of links 25 pivoted to a rotatable plate 26 secured to the spindle carryingthe handles 19. The plate 26 has a slot engaged by the latch 21. In this embodiment the flaps are swung inwardly in the manner shown in Fig. 6 when either handle 19 is turned.

I claim:

1. In a rolling shutter or similar device having an opening or doorway, a swinging door for closing the opening in said rolling shutter, means on one face of the door extending beyond the side edges thereof and adapted to engage one face of the shutter for preventing the door passing through the opening, flaps hinged to the other face of the door adapted to be moved to extend beyond the side edges of the door and engage the other face of the shutter for retaining the door in the opening, handle operated means on said door, a double-armed lever actuated by said handle operated means, and links connecting the ends of said lever with the free edges of said hinged flaps.

2. In a rolling shutter or similar device having an opening or doorway, a swinging door for closing the opening in said rolling shutter, means on one face of the door extending beyond the side edges thereof and adapted to engage one face of the shutter for preventing the door passing through the opening, flaps hinged to the other face of the door adapted to be moved to extend beyond the side edges of the door and engage the other face of the shutter for retaining the door in the opening, moving means on said flaps, handle operated means on said door, a double-armed lever actuated by said handle operated means, and links connecting the ends of said lever with the moving means on said hinged flaps.

3. In a rolling shutter or like screen having an opening, a wicket door, a jamb for said door, hinges connecting said door and jamb, said door carrying at least one pivoted stop of flap form adapted when operative to extend from the door and abut against the shutter to prevent movement of the door through the opening in the shutter, handle operated means on said door for moving said stop from its extended position so as to render it inoperative, and means connecting said stop to said handle operated means.

4. In a rolling shutter or like screen having an opening, a wicket door in said opening, a jamb for said door, hinges connecting said door and jamb, flap-like stops hinged to the edges of said door and adapted to be shifted to engage the.

jamb and prevent opening of said door, handle operated means on said door for actuating said stops, and links connecting said means and stops.

5. In a rolling shutter or like screen having an opening, a door janib fitted in said opening, a wicket door for closing said opening, hinges connecting said door and jamb, flap-like stops hinged to the edges of said door and adapted when in operative position to engage the door jamb and prevent the opening of said door, handle operated means on said door for swinging said hinged stops to operative and inoperative positions, locking mechanism associated with said means, and links connecting said means and stops.

6. In a rolling shutter or like screen having an opening, a door jamb fitted in said opening, a wicket door for closing said opening, hinges connecting said door and jamb, flap-like stops hinged to the edges of said door and adapted when in operative position to engage the door jamb and prevent opening of the door, handle operated means on said door for swinging said stops to inoperative position, and links connecting said means and stops, said links being pivoted both to a member rigid with the handle and to a member hinged to the flaps.

'7. In a rolling shutter or similar device having an opening or doorway, a swinging door hinged to the shutter for closing the opening in said rolling shutter, means secured on one face of the door for preventing the door passing entirely through the opening in the shutter, stops hingedly mounted on the other face of the door and means for swinging the stops to an inoperative position within the periphery of said door and to an operative position in which they project beyond the periphery of the door and engage the sides of said opening to retain the door therein.
